摘要

The aim of this work is to test the accuracy of numerical previsions made following two different approaches: the first is an Image Source code, built up around the computing formulas contained in the new ISO DIS standard 9613 parts 1 and 2. The second one is a general purpose Pyramid Tracing code, called RAMSETE, that is suitable both for indoor and outdoor simulations.
